Suse 10.0 user, need HELP making network connection active


everyone,,,,,
installed a new motherboard, installed linux 10.0 by CD, YAST installed a network connection (although there is no way to know how to pick the LAN card out of the list) i had to use the "ADD" button, the card was not "detected" ...
it resides on the sys tray as an "X" when i click on the eth-0 system named connection nothing happens ...
when i ck for connectivity i get an error message that "no active connection" ... so i have a Motorolla Cable Modem with an IP on it and a network card set up but Suse tells me it is not active .. i thought to make the connection active all i needed to do was click the eth-0 connection in the dialog box ......
i will try the if config command from shell ... any other suggestions??
also, ip is 127.0.0.1 (loopback) and when i try the ifconfig command i get a sub net mask of 255.0.0.0 ....
when i use ifcongig eth0 up in shell i get "no device exists" ...
the on-board LAN is ENABLED in the BIOS ....
any help would be greatly appreciated !!!!!!!
i desperately need to upgrade from the mirror servers to 10.3 i am having alot of trouble with my new IDE drive and the LCD monitor horizontal refresh rates ....
thanks,
dave

Run the "sudo /sbin/lspci -v" command to determine the make & controller that the NIC uses. You may simply need to modprobe the kernel module. If this is a grand spanking new model motherboard, you may need to update to a more recent kernel or install 10.3 so that it is supported.

so just go buy a new set of setup cds????

how would i get 10.3 without being able to access the internet through the network card to download it???
do i need to just go buy new cd's???
i installed a netgear card and same result as the on-board one ...
had a thought though ... is it possible that since the motherboard/hdd is not supported in 10.0 that when i use cd1 to boot from that this procedure disables the network adapters ????
all i'm left with is 127.0.0.1 and 255.0.0.0 with one adapter in hwinfo is lo the other loopback, neither the onboard LAN or the Netgear is being seen by Linux ....
i will keep the line command though, i get much the same info from hwinfo ..... just seems that nothing i do including rcnetwork restart and ifup eth-0 and ifup eth-netgear get Linux to recognize the two cards .... again it might be because i am booting from the CD .... and this is because i cannot get the system booted from the HDD .... thought i could boot with the CD and get to the internet and downloac 10.3 ... but i guess i thought wrong ....
so, my option is to go and buy some newer linux cds ????
and what is "modprobe" the kernel ... how is this accomplished ,,, have not heard of this before ....
thank you for your response and long-live Linus and Linux

Please post the lspci results for your interface. The first step is to identify the device. The next step is to determine which kernel module controls the device. Then you can enter the "lsmod" command to determine if that kernel is loaded.

If may be that the device is new and not recognized but a driver you do have would work. In that case, you could add the name of the module to /etc/sysconfig/kernel.
Code:
## Type:                string
## ServiceRestart:      boot.loadmodules
#
# This variable contains the list of modules to be loaded
# once the main filesystem is active
# You will find a few default modules for hardware which
# can not be detected automatically.
#
MODULES_LOADED_ON_BOOT=""
The "modprobe" command is run as root to load in kernel modules. Using Google, an HCL or the kernel source documentation you could identiy which module needs to be loaded. Then running "sudo /sbin/modprobe <module_name>" will cause the device to be recognised. After that, rerun YaST2 to configure the device.

Another thing that can trip you up is using a kernel boot option in grub such as "noacpi" which may disable autodetection.
